摘要：
Adverse outcomes in heart failure occur more frequently with QRS prolongation. The results of our study have shown that 1/4 of community. hospital patients with heart failure of sufficient severity leading to hospitalization have a QRS duration of greater than or equal to120 ms and that this degree of QRS prolongation is associated with substantially more severe left ventricular (LV) systolic dysfunction, LV dilation, and mitral regurgitation.
